Ingrid claims that Cosine (negative StartFraction pi over 2 EndFraction + y) = sine (y). Review Ingrid’s steps in verifying her claim. A 2-column table with 5 rows. Column 1 has entries Step 1, step 2, step 3, step 4, step 5. Column 2 has entries cosine (negative StartFraction pi over 2 EndFraction + y) = sine (y), cosine (negative StartFraction pi over 2 EndFraction) cosine (y) minus sine (negative StartFraction pi over 2 EndFraction) sine (y), 0 times cosine (y) minus 1 times sine (y) = sine (y), 0 minus sine (y) = sine (y), sine (y) = sine (y).

Which statement describes Ingrid’s claim that Cosine (negative StartFraction pi over 2 EndFraction + y) = sine (y) and her steps in verifying her claim?
